Abstract

Nowadays, the robots are widely used in many areas, where Human life cannot be compromised. In the Rescue operation, the robots need to search for the trapped humans. The A-star algorithm and it’s variations like Iterative Deepening A-star (IDA-star), Jump Point Search (JPS), etc. are the most popular algorithm in the field of Path-finding in Maze. In those rescue operations, the efficient path between the robot and the trapped person need to be found. But due to their heuristic nature, one cannot predict that whether the output of those algorithms will be cost-efficient or not. Here we are presenting a modified cost function of A-star algorithm in such a way that it will produce a path with less number of rotations.
